Sorry for bad info. I have the choke door open. only one air door on carb. I have 1412 performer. I ordered metering rods per the manual. In the carb now I have .071/.047 . The next two step to rich rods are .068/.047 , .065/.047 , .070/.042 and .070/.037 without changing the jets. Thanks for that info. when I read the manual I didnt get it until you spelled it out. After I get all this worked out then I will hook up the vacuum advance and tune it back counter clockwise if needed. THANK s
Dale
